STAIR-CARPET FASTENER.

OSZAOL To all whom it may concern:

Be it known that I, HARRY C. ADAMs, a citizen of the United States,residing at New York city, New York, have invented certain new anduseful Improvements in Stair-Carpet Fasteners, of which the following isa clear, full, and exact description.

My invention relates to a stair-carpetfastener, which is to hold acarpet on a flight of stairs.

My object is to improve upon the construction of fastener set forth inmy prior patent 587,633.

In the drawings, Figure 1 shows two steps of a stairway with twofasteners thereon in their normal carpet-engaging position; Fig. 2 is asection on the line 22 with the looking device in the locking position;Fig. 3 is a similar view with the lower toothed bar in its foldedposition and unlocked. Fig. 4 is a perspective view of the lower bar andpivoted locking arm in the positionsimilar to that in Fig. 2; and Fig. 5is a detail.

In the use of such a fastener, which consists, essentially, of twotoothed bars or plates fastened in the angle between the tread and riserand with the teeth of the bars projecting across the angle, the two barsbeing separated so that a fold of carpet may be inserted therein. It hasbeen found that when the carpet is removed the lower bar interferes withthe feet of a person coming down the stairs and sometimes catches theskirts of a womans dress, and it is desired to make one of the bars(preferably the lower bar) adjustable so that it may be moved out of itscarpet-engaging position and at the same time may be locked in itsnormal carpet-engaging position.

In the drawings, 1, 1 are the risers, and 2, 2 the treads of a stairway.The toothed bars of a fastener are indicated at 3 and 4:. These aresuitably secured in the angle near the junction of the tread and riserwith the toothed portions extending across the angle and toward eachother, that is, in such a manner as to hold a fold of the carpet betweentheir separated edges. For example, in the manner indicated by the fold5 of the carpet in Fig. 2. The means for securing the bars in positionis preferably one or more devices which connect the bars, and I haveshown such in the angle bars 6 which are fastened to the riser by screws7. In order that one of the bars (preferably the Specification ofLetters Patent.

lower one 4) may be moved out of its carpetengaging position, I haveprovided a pivot connection between the lower bar and the means whichsupports said bar, in this case its brackets 6, as indicated at 8, sothat the bar 4 may stand in its normal carpet-en gaging position shownin Fig. 2, or be folded down into the position shown in Fig. 3 where itwould be out of the way. This is the construction I prefer. In order tolock the bar in its normal carpet-engaging position, I have provided astop portion 9 and a pivoted detcnt 10, which has an upturned end 11which may be thrown against the inner side of the bar, as indicated inFigs. 2 and 4, so as to hold the same from collapsing.

The carpet may be laid on the stairway, and at each angle between thetread and riser a fold of the carpet'is forced between the toothededges, as indicated in Fig. 2, which will slightly enter the back of thecar pet to hold the same in position without any other fastening meansand the carpet will entirely hide the fastener so that no fasteningmeans will be visible from the front. The carpet may be detached byreversing the operation, or merely loosening it from the bottom andshaking it.

I do not limit myself to the form of the invention shown in thedrawings, as I am aware that the invention may be embodied in otherforms without departing from the spirit of my invention as claimed.

What I claim is 1. A stair-carpet fastener comprising a pair of toothedbars, supporting means to which said bars are attached, said barsstanding with their toothed portions eX- tending toward each otheracross the angle between the tread and riser and separated to receivethe fold of a carpet, said supporting means comprising a movableconnection to one of said bars whereby said bar may be moved out of itscarpetengaging position, and a locking device to hold it in its normalcarpet-engaging position.

2. A stair-carpet fastener comprising a pair of toothed bars, supportingmeans to which said bars are attached, said bars standing with theirtoothed portions extending toward each other across the angle betweenthe tread and riser and separated to receive the fold of a carpet, saidsupporting means comprising a pivotal connection to IOU one of said barswhereby said bar may be folded toward the other bar, and a lockingdevice to hold it in its normal carpet-engaging posltion.

3. A stair-carpet-fastener comprising a pair of toothed bars, supportingmeans to which said toothed bars are attached, said bars standing withtheir toothed portions extending toward each other across the anglebetween the tread and riser and separated to receive the fold of acarpet, said supporting means comprising a movable connection to one ofsaid bars whereby said bar may be moved out of its carpet-engagingposition, and a locking device to hold it in its normal carpet-engagingposition, said locking device being connected with said bar whereby itand said bar may be removed together.

4. A stair-carpet-fastener comprising a pair of toothed bars and meansconnecting said bars and adapted to secure the same in the angle betweenthe riser and tread with the toothed portions extending toward eachother across the angle and separated to re ceive the fold of carpet, thelower bar being pivoted to said connecting means and adapted to befolded downward out of its carpetengaging position, and a lock forholding the same in its normal position and comprising a detent pivotedto the support of said bar on the inner side of the same and adapted tobe thrown outward into engagement with said bar to hold the same inposition.
